Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
See also Fig. 1～shown in Figure 3, in the present embodiment, described refine on line is comprised of the degasification rotating disk 2 that degasification rotating shaft 1, degasification rotating shaft 1 end, lower end connects with degassing rotor.
In the present embodiment, described degasification rotating shaft 1 by the center with counterbore 11 and upper end with internal thread 12, lower end with forming with circular shaft that degasification rotating disk 2 is connected with outside screw 13.
See also Fig. 4～shown in Figure 7, in the present embodiment, described degasification rotating disk 2 is collar plate shape, the air receiver 211 of being offered by rotor body 21, rotor body 21 centers, the lower semisection of described air receiver 211 radially be arranged with respectively some radially distribute and and the air drain 212 that connects of described air receiver 211, the cylinder between two adjacent air drains 212 on be arranged with respectively and somely only form with the stirrer gear 213 that described air receiver 211 does not connect with extraneous perforation with outer side and bottom surface.
In the present embodiment, the counterbore 11 that described air receiver 211 is arranged with along the center by rotor body 21 tops, the screw thread 12 of counterbore 11 inwall moulding form.
